Beit known that I, HENRY D. TnRanLL, of Govington, in the county ofNewton and State of Georgia, haveinventedanew and Improved ConvertibleFlow, of which the following is a full, clear, and exact description.

The object of my invention is to lessen the outlay required foragricultural implements, and iorkeepingthem in working order,thcrebypromoting the more economical cultivation of the soil for a variety ofcrops.

The invention consists in a convertible plow made with a foot plate orpiece having edge flanges, and an oiiset shouldered end allowing theattachment thereto of interchangeable side plates or wings andplow-points of various kinds, so as to form, as required for use, ascooter or bull-nose plow, a turningploma shovel-plow, and ascraper-plow; and also permitting small or short plow-points to be used,and to be renewed when worn.

The invention consists, also, in particular constructions of the plowfoot -plate and of the several interchangeable mold-boards and wings forconnecting them by bolts. so as to be securely held and readily removed;and also in particular combinations of the interchangeable mold-boardsand wings and plow-points, all as hereinafter fully described andclaimed.

Reference is to be had to the accon'ipanying drawings, forming part ofthis specification, in which similar letters ofreference indicatecorresponding parts in all the figures.

Figure 1 is a perspective View of the lower end of a plow stock with myimprovements attached as a turning-plow. Fig. 2 is a perspective Viewshowing the arrangement of the parts as a shovel plow. Fig. 3 shows theparts arranged for a scraper-plow. Fig. 4 is an enlarged longitudinalsectional elevation on the liner m, Fig. 3. Fig. 5 is a perspective Viewof the turn-plow 1nold-board, and Fig. 6 is a perspective view of one ofthe wings or side plates of the shovelplow.

The letter A indicates the foot-plate or scooter-body, which is to beheld to any suitable plow stock or standard B-partly shown in Fig. 1-bya strong bolt, 0, passed through the stock and receiving a nut at theback of the stock, and the tapered head of the bolt. enters acorrespondingly-shaped recess, 0, in

the foot'plate A, so as to draw the plate firmly to the stock and beflush with the face of the plate, to avoid catching the earth which mayrise to it when the plow is at work, and the top of the foot-plate comesagainst the usual shoulder, (1, ofthe stock to steady the plate, so thatone bolt. C, will hold it firmly without lateral play. At each edge thefoot -plate A has a backwardlyextending fiange, D, which has lugs (Z,provided with suitable holes, (2, for the passage of bolts by which tosecure to one or both edges of the foot-plate the interchangeable wingsor mold-boards, as hereinafter more fully explained. I make a backwardoffset in the face of the foot-plate, near the bottom, for about thethickness of the interchangeable plow-poi nts, as at E, and I undercutthe shoulder of said offset or recess, as at a, so that thecorrespondingly inclined or beveled top edges of the plow-points willlook into and under the shoulder, for allowing the points to be heldfirmly to the foot-piece by a single bolt, F, the head of which iscountersunk into the plowpoints, as shown in Fig. at, to allow the earthi'ree passage over the face of the plow and prevent wearing away of thehead of the bolt. The pointless foot-plate A is bolted to the stock 13,so as to have the same set as the ordinary scooter'plow plate, and so asto receive any desired shape of plow-point-such as a scooter-point madein the shape of the lower ends of the ordinary scooter plow shares, suchas may be represented by so much of the plow-point in Fig. 1 ascorresponds to the width of the f0ot-piece Aor an ordinary double-curvedbull-nose plow-point, such as is represented in Fig. 3, may be connectedto the foot-plate by the bolt F.

The letter G- indicates a mold-board which has a flange, 9, providedwith holes 9 for the passage of bolts through them, and the upper andlower holes (1 at one side flange of the foot-plate A; and G is a broadplow -point, fitted to the offset E- and shoulder c, and held by a bolt,F, below the plate and the mold board, so that the parts A G Gconstitute together an eiiicient turning-plow, as in Fig. 1.

The letters H H indicate side plates, which have flanges h withbolt-holes h, as shown in Fig. 6, said plates being made in pairs, so asto be bolted to the flanges D of the foot-plate A at each side of it;and II is a broad shovelpoint, fitted to the offset and shoulder E 0,fastened by a bolt, F, and abutting the lower ends of the side plates, HH, as in Fig. 2, for converting the plow into'a shovel-plow.

The letters I I indicate scraper wings or blades, which have upwardly oroutwardly turned flanges z i, ranging obliquely at the bendto the frontcutting-edges, j, of the scraper, so that said edges incline backwardsuitably for working easily through the soil; and the flanges i 7; willbe bent upward or outward from the faces of the scrapenblades at varyingangles with their faces, to incline the pposite scrapers more or less tothe face of the foot-plate A, as the nature of the soil shall require.In stiff land the angle of inclina tion will not be so great, or will bemore obtuse, so that the soil can pass off easily, while for use in grayor sandy soil the angle of inclination will be more acute, or nearer aright angle.

By providing the flanges D D of the footplate A with three bolt-holes,d, as shown, I am enabled to fasten the opposite scraper blades, I Lbythe nutted bolts 7c,passed through the bolt-holes of flanges 2' eitherinto the two upper holes, cl, of said flanges D, for holding the bladesII at the top of the foot-piece A at each side, as in full lines in Fig.8, for deep plowing, or the fastening -bolts may pass through theflanges into the two lower holes, (1, of the flanges D,to hold thescraper-blades in the positions shown in dotted lines in Fig. 3, ornearer the plow-point, for shallow plowing, as will readily beunderstood.

I show in Fig.3 the bullnose plow-point I, fastened by the bolt F in theoffset E and against the shoulder 6; but the wider shovelplow point IIshown in Fig. 2 may be used with the scraper I I, if desired. \Vhentheplow-points are madeintegral or in one piece with the main body of thescooter'plow plate in the common way, the entire plate becomes uselessfor plowing purposes when but onethird of its length is worn away at thelower end; hence, by providing the foot piece or plate A and attachingseparate plow-points thereto,when the point is almost wholly worn. awayit may be removed easily by taking out the bolt F, and a new pointquickly be substituted, and one of the foot-plates Awill outlast many ofthe points, which may be interchanged one for the other as the workshall require,and, as the points made as I propose will cost verymuchless than an entire plow-plate, a considerable saving in the cost ofthe plowplates is secured; and by my method of fastening the removablepoints with an undercut or looking shoulder in connection with thefastening-bolt quite as strong an implement is provided as one made in asingle piece; and by providing the foot-bolt A with the aperturedflanges D D, permitting a variety of mold-boards and plow-plates to beattached to it, fewer agricultural implements as a whole will berequired; hence the soil may thoroughly be cultivated for a variety ofcrops at less expense.

I prefer to make the foot-plate A and the interchangeable points andside plates or wings in malleable-iron castings,but they may be made ofother cast or wrought metal,as desired.

Having thus described myinvention, whatI claim as new, and desire tosecure by Letters Patent, is-

1. As an improved article of manufacture, the foot-plate A, formed withthe apertured offset E, having undercut shoulder e, and with thebackwardlyextending edge-flanges D, hav ing apertures d, as set forth.

The combination, with the foot-plate A, formed with the apertured offsetE and the apertured edge-flanges D, of an interchangeable point andflanged wing, whereby various forms of points and wings are adapted tobe secured to the offset and flanges of the foot plate, substantially asherein shown and de scribed.

3. The combination, with the fo.ot-plate A, formed with the aperturedoffset E and the apertured edge-flanges D, of the'mold-board G, providedwith the apertured flange g g, and the point G, secured in the saidoffset, substantially as herein shown and described.
